Vortioxetine: From Major Depressive Disorder to Neurotic Disorder
One-Sentence Summary
Vortioxetine is a multimodal serotonergic antidepressant originally used for depressive and anxiety disorders. The TxGNN model predicts it may be effective for neurotic disorder, but no clinical trials and only 1 publication (a single case report) are currently linked to this prediction. Because “neurotic disorder” is a legacy, broad diagnostic label that overlaps with vortioxetine’s existing indications, this is better seen as a labelling overlap than a true new therapeutic opportunity.

Why is This Prediction Reasonable?
Currently, detailed mechanism of action data is not available in the data compiled for this report. Published reviews describe vortioxetine as a serotonin transporter (SERT) inhibitor that also acts on several serotonin receptors: 5-HT1A agonist, 5-HT1B partial agonist, and 5-HT3, 5-HT7 and 5-HT1D antagonist. This multimodal profile is plausibly relevant to both the depressive and anxiety components of neurotic conditions.
“Neurotic disorder” is an older, broad category that overlaps heavily with depression and anxiety disorders, which are vortioxetine’s established indications. The high TxGNN score most likely reflects this overlap rather than a distinct new use. No specific mechanism has been established for this label.
The other top-ranked predictions are also depression-related (neurotic depression, melancholia, dysthymic disorder). They are mostly on-label or near-label rather than genuine repurposing. Benign paroxysmal torticollis of infancy (score 0.9907) has no plausible mechanistic link, no trials and no literature, and appears to be a model artifact.
Clinical Trial Evidence
Currently no related clinical trials registered for neurotic disorder.

Safety Considerations
Drug Interactions: The interaction screening recorded 100 potential interactions. The main ones, from the 20 reviewed entries, are:
- Major: bupropion, lorcaserin, diethylpropion, dolasetron, palonosetron, phentermine
- Moderate: morphine, acetylsalicylic acid, dexamethasone, chlorpropamide, glimepiride, several insulins (aspart, degludec, detemir, glargine, glulisine), eliglustat, and bowel-preparation agents (picosulfuric acid, sodium sulfate, polyethylene glycol with electrolytes)
Other considerations from the literature:
- CYP2D6 and related pharmacogenetic dosing guidance exists (CPIC guideline).
- Reported adverse effects include hyperhidrosis, gastrointestinal effects and sexual dysfunction.
Please refer to the package insert for warnings and contraindications.
Conclusion and Next Steps
Decision: Hold
Rationale: The prediction rests on model output alone, with no trials and only one non-vortioxetine case report. “Neurotic disorder” is a legacy umbrella term that overlaps with vortioxetine’s existing depression and anxiety indications, so there is little distinct repurposing value to pursue.
To proceed, the following is needed:
- Clarify how “neurotic disorder” maps onto current diagnoses (for example, anxiety or depressive disorders), and evaluate those on-label uses instead
- Mechanism of action data from DrugBank
- Health Canada package insert warnings and contraindications, which are required before any safety screening
- Vortioxetine-specific clinical or observational evidence for the mapped condition
